龙溪口航电枢纽工程船闸输水系统设计

龙溪口航电枢纽工程的主要开发任务为畅通岷江航运通道，船闸作为该枢纽的唯一航运设施，是岷江通道畅通中的重要一环，故输水系统作为该船闸核心的组成部分，其重要性不言而喻。针对该船闸输水规模较大、水力指标要求较高的问题，对船闸进行水力学计算分析以及单体物理模型试验研究。结果表明，龙溪口航电枢纽船闸输水系统设计采用闸墙长廊道侧支孔输水形式是合理的，满足设计规范要求；闸室灌泄水时水流条件及阀门开启方式满足船舶安全通行需要。

Filling and emptying system design of ship lock in Longxikou Navigation-power Junction project

The main development task of the Longxikou Navigation-power Junction project is to smooth the navigation channel of the Minjiang River.Since the ship lock is the only shipping facility at this junction and an important part of this channel,the importance of the filling and emptying system as the core component of the ship lock is self-evident.In response to the large-scale filling and emptying,and high requirements for hydraulic indicators of the ship lock,we carry out the hydraulic calculation analysis and the study of a single-body physical model test on the ship lock.The results show that it is reasonable to employ the support hole filling and emptying form of the gate wall long corridor side for the filling and emptying system design of the ship lock in the Longxikou Navigation-power Junction,which meets the design specifications.The water flow conditions and valve opening method during the filling and emptying of the ship lock chamber also meet the needs of safe ship passage.
